[For the first time, Bucky feels a slight tendril of tension snake up his spine. Steve works for a government agency? It's a stupid reaction, he just said that he's a glorified file clerk and plenty of people work for the government, it's just a knee-jerk reaction. Like Steve isn't as safe as the image he projects.

It probably shows in the way that his hand tightens around his coffee mug, even if he keeps the smile at his lips.]

You don't really look like a file clerk. All the clerks I've ever met have been assholes who pretty much chew bitterness for breakfast and then spit it out at everyone all day.

[Just probing for more information there.]
